A child’s retina is over 100% more sensitive to blue light than an adult according to peer reviewed studies. Overexposure to high frequency blue light from digital devices may disrupt sleep, learning and behaviour in children. Sleep+ is our signature blue and green light blocking lens, eliminating 100% of blue and green light between 400nm to 550nm. This is the exact range that has been shown in clinical trials to disrupt melatonin and negatively impact our sleep. Sleep+ are the best blue light blocking glasses available for optimising sleep, recovery and balancing hormones. Sleep+ is to be worn 2-3 hours before bed for optimal results after just one evening’s use. Sleep+ is also a key tool in managing jet lag and is used by the world’s most optimal athletes and wellness professionals for improved sleep, focus and recovery. Our Sleep+ collection is available in non-prescription, prescription and reading magnification options.
